Simplify's Take

What believers are saying

  • Scalable opened an AI distribution channel in August 2026, letting customers connect investment accounts to external assistants.
  • Scalable expanded fund design in August 2026 with asset manager DWS: their fund targets twice global stocks' daily returns.
  • Graduates explore several teams: Scalable runs a 12-month program with three job rotations and a shared autumn start.

What critics are saying

  • AI distribution has external gatekeepers: Scalable says third-party assistants operate outside its control and restrict some functions.
  • Berlin client-service stability is limited: the Tax and Trading manager role starts with a two-year fixed term.
  • Client-service hours extend into evenings: Berlin's Tax and Trading manager role schedules weekday shifts between 8am and 8pm.

What makes Scalable Capital unique

  • Scalable runs exchange infrastructure: it handles technical operations for the European Investor Exchange at Hanover Stock Exchange.
  • Scalable reaches clients through other banks: partners use its wealth platform under their own brands.
  • Scalable packages crypto as securities: its exchange-traded products track cryptocurrencies including Bitcoin and Ethereum.
